RIVERHEAD - A man has pleaded guilty today to killing his girlfriend and her son inside their apartment in December 2011.

Jerry Lewis admitted to stabbing to death 21-year-old Shakeela Planter and beating to death 23-month-old Jaiden Planter, then leaving them both wrapped in plastic inside their North Bay Shore apartment.

Shakeela’s mother, Pamela Planter, says she feels justice has been served.

Under the terms of the plea agreement, Lewis will spend 30 years to life in prison for the killings.

Lewis is expected to be sentenced on April 3. Officials say if he is ever paroled, he will be deported back to his native Jamaica.
